CAR-PLATFORM.

SPECIFICATION forming part of Letters Patent No. 303,108, datedAugust 5,1884.

Application filed June 17, 1884.

supporting and adding strength to the sliding platform.

The invention also consists of the special construction ofthesupporting-rods on which the springs are placed; also, of theconstruction, arrangement, and combination'of parts, all as hereinafterdescribed and set forth in the claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which si milarletters of reference indicatecorresponding parts in both the figures.

Figure l is an inverted plan view of the ends of the bottoms of tworailroad-carshav- Y ing my improved sliding` platforms applied thereto;and Fig. 2 is a sectional elevation of the saine, taken on the line :va: of Fig. l.

The bottom boards, A A, edge timbers or sills, B B, cross-timbers C C,parallel bars D D, and sliding platforms F F are of substanl tially thesame construction as shown and described in the above-mentioned patent.

In addition to the bars DD, I provide also thevparallel bars E E, which,together with the said bars D D and the rods G G, support the platformsF. p

The rods G G, instead of being made plain, as in the above-mentionedpatent, are made round at their forward ends, as shown at g, and theyare formed with the shoulders g iu the center, and are attened at theirrear ends, back of the shoulders g', as shown at g2, through whichflattened portions the screw-bolts a a pass for securing the rods to theunder surfaces of the cross-timbers C, as shown clearly in the drawings.The platformsFare secured to the round portions y of the rods G by thecleats orv boxes b t', and upon the rods G, be-

allel bars E by the cleats o c, as shown in Fig.

l, which are loose upon the bars, so as not to interfere with the freeback and forward movelments of the platforms F. The outer edges of theplatforms F are faced with the plates d il, of metal, and provided withthe friction-balls c c, the saine as in the said patent.

` Between the parallel bars D D are placed the draw-heads J J, which arepivoted at j j, and held upon the cross-plates K K, secured to the outerends of the barsD D. The drawheads of the two cars are forced towardeach other by the coiled springs f f, and they are held from beingforced too far by the links or hooks h le, attached to the draw-heads,and hooked linto the staples i i', as shown clearly in Fig. 1.

The platforms F are adapted to slide backward upon the rods G G, againstthe tension of the springs H H, a distance of three inches, orthereabout, which permits the cars to couple and passfreely aroundcurves inthe railroad;

and, owing to the action of the springs and the sliding movement of theplatforms, the space between the adjacent edges of the platforms is keptentirely closed when the cars are coupled.

Another advantage of the sliding springplatforms is that they secureeasy starting and stopping of the train without bumping, there bydiminishing the wear and tear on the cars and locomotive; and thespring-platforms act also to reduce the force of concussion in case ofcollisions, thus obviating a large portion of the damage to life andproperty.

Having thus described my invention, I'claiin as new and desire to secureby Letters Patent- 1. The combination, with the sliding platforms F,rods G, springs H, and parallel bars D, of the parallel bars E, arrangedsubstantially'as and for the purposes set forth.

2. The rods G, formed with the round portions g, shoulders g, and datportions g2, by which latter they are secured to the crosstiinbers C,substantially as described.
